본 연구의 목적은 정보기술 구조와 기업의 경쟁전략사이의 관련성을 조사함으로써, 기업의 경쟁전략의 형태에 따라서 정보시스템이 어떠한 형태를 취하느냐를 조사하는데 있었다. 다시말해서 공격형의 전략을 채택한 기업은 정보시스템의 구조가 분산화된 형태, 방어형의 전략을 채택한 기업은 집중화된 형태, 분석형의 전략을 채택한 기업은 중간형태를 취할 것이라는 가설을 설정하였다. 본 연구에서 나타난바에 의하면 정보시스템 구조는 경쟁전략과 상당한 관계가 있고 특히 정보기술활동의 집중화 정도는 경쟁전략과 깊은 관련성이 있다. 서로 다른 경쟁전략을 택하는 기업은 서로 다른 정보시스템을 채택하는 경향이 있음을 알 수 있다. 보수적인 경쟁전략을 가진 조직의 정보시스템구조는 적극적인 경쟁전략을 가진 조직의 정보시스템구조 보다는 더욱 집중화되어 있다. 다시말해서, 보수적인 조직의 사용자 부문은 적극적인 조직의 사용자 부문보다는 그들의 정보기술활동에 대한 책임성이 덜하다. 이러한 사항을 기초로하여 본 논문에서는 보수적인 경쟁전략은 정보시스템에 대한 책임성의 집중화에 영향을 미친다고 예측할 수 있고 반면에 적극적인 경쟁전략은 정보시스템에 대한 책임성의 분권화에 영향을 미친다고 예측할 수 있다. 일반적으로 본 연구의 결과는 조직변화개념에 대한 부가적인 도움을 주지만 그러나 경쟁전략뿐만 아니라 조직의 다른 상황변수도 정보시스템구조에 영향을 미친다는 것을 지적해 두고자 한다.

Information security has become an important issue in the world. Various information and communication technologies, such as the Internet of Things, big data, cloud, and artificial intelligence, are developing, and the need for information security is increasing. Although the necessity of information security is expanding according to the development of information and communication technology, interest in information security investment is insufficient. In general, measuring the effect of information security investment is difficult, so appropriate investment is not being practice, and organizations are decreasing their information security investment. In addition, since the types and specification of information security measures are diverse, it is difficult to compare and evaluate the information security countermeasures objectively, and there is a lack of decision-making methods about information security investment. To develop the organization, policies and decisions related to information security are essential, and measuring the effect of information security investment is necessary. Therefore, this study proposes a method of constructing an investment portfolio for information security measures using game theory and derives an optimal defence probability. Using the two-person game model, the information security manager and the attacker are assumed to be the game players, and the information security countermeasures and information security threats are assumed as the strategy of the players, respectively. A zero-sum game that the sum of the players' payoffs is zero is assumed, and we derive a solution of a mixed strategy game in which a strategy is selected according to probability distribution among strategies. In the real world, there are various types of information security threats exist, so multiple information security measures should be considered to maintain the appropriate information security level of information systems. We assume that the defence ratio of the information security countermeasures is known, and we derive the optimal solution of the mixed strategy game using linear programming. The contributions of this study are as follows. First, we conduct analysis using real performance data of information security measures. Information security managers of organizations can use the methodology suggested in this study to make practical decisions when establishing investment portfolio for information security countermeasures. Second, the investment weight of information security countermeasures is derived. Since we derive the weight of each information security measure, not just whether or not information security measures have been invested, it is easy to construct an information security investment portfolio in a situation where investment decisions need to be made in consideration of a number of information security countermeasures. Finally, it is possible to find the optimal defence probability after constructing an investment portfolio of information security countermeasures. The information security managers of organizations can measure the specific investment effect by drawing out information security countermeasures that fit the organization's information security investment budget. Also, numerical examples are presented and computational results are analyzed. Based on the performance of various information security countermeasures: Firewall, IPS, and Antivirus, data related to information security measures are collected to construct a portfolio of information security countermeasures. The defence ratio of the information security countermeasures is created using a uniform distribution, and a coverage of performance is derived based on the report of each information security countermeasure. According to numerical examples that considered Firewall, IPS, and Antivirus as information security countermeasures, the investment weights of Firewall, IPS, and Antivirus are optimized to 60.74%, 39.26%, and 0%, respectively. The result shows that the defence probability of the organization is maximized to 83.87%. When the methodology and examples of this study are used in practice, information security managers can consider various types of information security measures, and the appropriate investment level of each measure can be reflected in the organization's budget.

This study is to review the attitude of consumers on the crisis response strategy (defensive vs. receptive) that the company implements in crisis situations. Also, the interaction between the crisis response strategy that the company implements and the crisis type of companies (corporate ability vs corporate social responsibility) was discussed. In addition, the interaction between the messages (abstract vs. concrete) of public interest associated marketing implemented prior to crisis situations and the crisis response strategy implemented after crisis situations was discussed. And these results were reviewed to see if the same result can come out after controlling the involvement on consumer's public interest associated marketing as a covariate. The main results of this study are as follows. First, regarding the crisis response strategy, in the company's crisis response strategy, the receptive attitude was more favorable for the consumer's attitude than the defensive attitude. Second, it was seen that there is a significant interaction between the crisis response strategy of companies and the crisis type of companies. Third, it was seen that the crisis response strategy of companies has a significant interaction with the message type of public interest associated marketing. Lastly, the involvement showed a significant effect as a covariate and the interaction between the crisis response strategy of companies, the crisis type of company and the message type of public interest associated marketing can be confirmed even after controlling the involvement. In the conclusion of the study, the direction on implications, limitations and future.

SDI에서 GPALS로의 전환은 미국의 안보 전략의 변화이자, SDI 계획의 돌파구를 마련하기 위한 시도로 보여진다. GPALS가 표방하는 목표는 소련뿐만 아니라 제3세계 국가들에 의한 고의적, 우발적, 또는 비인가된 미사일 공격에 대해 미국 본토 및 해외 주둔 미군, 그리고 우방국 및 동맹국 등을 방호한다는 것이다. 따라서 GPALS로 인해 SDI는 최초의 논리인 "방호"로 복귀한 셈이다

Based on the development of SNS in Mobile and Internet, crisis management is regarded as an important issue that determines the rise and fall of businesses. This study aims to contribute to more efficient implementation of crisis management messages by examining the relationship between the strategy of crisis management communication and the level of specificity of the message. The study found that consumers evaluated the crisis-hit company's acceptance communication strategy to show a higher level of integrity, reliability and appropriateness than the defensive strategy. However, this main effect is mediated by the specificity (high specificity vs. low). Specifically, consumers' assessment of crisis management messages and information-seeking behavior were found to be most favorable when used in a mixture of acceptance strategies and high specificity. Conversely, the lowest effect was the combination of defense strategy and high specificity. Based on these results, the theoretical discussions is described for crisis management practitioners of enterprises and organizations.

물관리 일원화, 물관리기본법 제정·시행 등 우리나라 물관리 체계의 혁신기에 정책의 구심점 역할을 수행할 통합 물관리 전략 마련이 요구됨에 따라, 최근 관계부처 합동으로 「제1차 국가물관기본계획(2021~2030)」을 수립하여 공표·발간되었다. 국가물관리기본계획에서는 유역단위의 물관리를 원칙(12대 기본원칙 중(中))로 하며, 물관리 3대분야(수질·수생태, 이수, 치수)에 대한 추진전략을 수립하였다. 또한, 지속가능한 물관리 체계를 구축하기 위해 추진전략별 주요 관리지표를 설정하였으며, 이를 통해 물관리 방향을 정립하고 분야별 관련 및 하위계획과의 일관성·정합성을 유지하고자 하였다. 이에 본 연구에서는 추진전략별 주요 관리지표 중, 유역 재해안전도와 관련하여 하천범람에 대한 기존의 치수안전도의 한계점을 검토하고 유역단위의 치수관리 현황을 평가 할 수 있는 방안을 마련하고자 하였다. 과거 유역종합치수계획에서의 치수안전도는 홍수피해잠재능(PFD)을 적용하여 등급별 홍수방어대책 수립방향 및 하천의 설계빈도 조정을 검토하였으며, 홍수피해잠재능(PFD)의 실무적 적용 어려움(산정인자 다(多)), 설계빈도와의 연계성 부족, 치수단위구역의 공간적 정확성 미흡 등에 대한 개선·보완의 의견이 제기되어 왔다. 또한, 유역내 전체하천이 아닌 주요 하천을 대상으로만 치수안전도 설정하여 유역단위의 치수관리에 한계가 있으며, 하천 전체구간의 설계빈도 상향에 따른 홍수방어대책이 비경제적인 것으로 판단된다. 따라서, 기존의 치수안전도의 한계점을 개선하기 위하여 홍수피해잠재능(PFD)의 산정인자 단순화, 홍수위험지도를 활용을 통한 치수단위구역의 공간적 정확도 향상 및 치수단위구역별 설계빈도 조정 가능 등의 개선방안을 검토하였으며, 빈도별 치수단위구역의 홍수피해잠재능(PFD)의 통계적 특성 분석을 통해 등급 설정 및 설계빈도 조정 기준을 제시하였다. 그리고 유역내 전체하천에 대한 치수단위구역별 치수안전도를 설정하고, 중권역 단위의 치수안전도를 평가하여 유역단위의 치수관리 현황을 정량적으로 제시함에 유역 재해안전도로 활용이 가능할 것으로 판단된다.

The global automotive industry has suffered various crises such as products defects and unethical company management. In order to examine the effectiveness of crisis communication strategy of an automotive company with Chinese consumers who occupy the largest proportion in the global market, this research analyzed the influences of crisis responsibility, crisis types, and crisis communication strategy on attitudes to a company, intentions of negative communication, and intentions to participate in a boycott. A 2(crisis responsibility: high/low) × 2(crisis types: corporate ability/corporate crisis responsibility) × 2(strategy: defensive/accommodative) experimental design was conducted with 1,600 Chinese students in Seoul. High crisis responsibility and corporate social responsibility crises were related to unfavorable attitudes to a company, higher intentions of negative communication, and higher intentions to participate in a boycott. Crisis responsibility and communication strategy showed a significant interaction. When crisis responsibility was high, the accommodative strategy was more effective than the defensive strategy. When crisis responsibility was low, there was no difference between the strategies. Corporate social responsibility crises found no difference between the strategies regardless of the crisis responsibility level. In the case of corporate ability crises, the accommodative strategy was more effective for the high crisis responsibility crisis.
